What the Electronic Power Steering (EPS) Light Means on a Peugeot 408

The EPS (electronic power steering) light on a Peugeot 408 indicates a fault in the electric steering assist. Steering can become noticeably heavier, and the system may need a diagnostic reset or repair.

How Urgent Is the Electronic Power Steering (EPS) Light?

In terms of priority, treat this as a high concern on your Peugeot 408. The single most useful thing you can observe is whether the Electronic Power Steering (EPS) Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Peugeot 408 drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
